Value for money is what you're getting here, and that means a trade-off in the quality of light, build quality and functionality.
There’s a large and somewhat cumbersome quick-release mounting that insisted on coming loose on a regular basis, but a little dab of thread lock soon stopped that.
The amount of light it puts out isn't bad and the beam pattern has a reasonable hotspot in the middle for pretty good reach down the trail (10-15m), but the peripheral spread has a sharp cut-off and visibility from the side isn’t great. Combined with a flood on a helmet, performance was alright.
The main issue that we have with this light is the switching. It uses a rocker switch on the back of the light, and in order to change from one mode of operation to another you have to turn the light off, and then turn it back on again.
Quite probably the most bizarre and, to be honest, the most daft way of switching modes of operation we have ever seen. Plunging yourself into darkness on that fast downhill bit as you try to ﬁnd the high power setting by going through the other four modes is something we can heartily recommend you don't do.
